Many features and options of GTBB inverters are the same as for off-grid inverters—some GTBB inverters can be used as off-grid inverters. There will simply be some programming differences to let the inverter know whether it needs to interconnect with the grid.

dear Lena
i have question may leads us to debate i hop any one with good understanding & experience in solar power can give me good productive answer ,,
we all know that the new interactive BB grid tie inverter has 2 AC input , one usually used for gird and the second one used for Diesel generator as standbye power supply ...in case no wind or no grid .
here i want suggest new option , which i hop we can share opinions and solutions ...
i want use the main AC input relaying on my solar power which generates 230 AC 10 KW and will use the other AC input for the grid ,,incase my solar power supply fails for any reason i can relay on the grid immediatly
thru this way i will avoid the losses from the power generation source from the solar power cells thru charge controler , charging batteries and then inverter ,,or even using DC from my solar to feed the battery

i think this model can work with outback power and SMA ..i wish to know this wrong , possible or not ,,,better or not

what or how u see guys this suggestion ? am i crazy or stupid ,,,thanx for sharing
thanx
